JAVA 1. Discuss what a programmer-defined class would look like. Provide a code sample for a class that has a constructor, fields, and methods to support your point of view. 2. Discuss what inputs the main( ) class program should have. How will those inputs get passed to an object of the class? Provide a code sample to support your answer.

Java program: The class diagram with four classes Mammal, Human, Student and Doctor is given. The Mammal class is given as well. Write down the remaining classes as described in the class diagram. The fields and methods for each class is given in the attachment. //in Mammel.java Public interface Mammal{ public double hairColor(): }   1.

USING JAVA

Your task is to develop a Tic-Tac-Toe (also called as “Noughts and Crosses”) game in Java using Swing. In this assignment, you are asked to implement a single-player version of the Tic-Tac-Toe game with easy-to-use graphical user interface (GUI). One player will be the user and the second player will be artificial intelligence (AI), namely, the computer. The entire procedure of the implementation has been split into three tasks with detailed description and explanation provided. By completing the three tasks, you will develop your own Tic-Tac-Toe game. Task 1: GUI ImplementationPlease implement a GUI satisfying the following requirements.• A menu bar with two buttons “Reset” and “Quit”. User can click the “Reset” button to restore the software to the initial status. User can software the game by clicking the “Quit” button;• The top pane is an information board to display username and present some basic guidance to the user about this game. The information board will also print out the…

JAVA Language: UML Diagram

Design, implement and test a class that can be used to hold information about a musical note. Test it with an appropriate driver program. DESIGN REQUIREMENTS A programmer MUST be able to set and retrieve the length of the note and the value of the note. The length of a note may be a sixteenth note, eight note, quarter note, half note, or a whole note.  The note’s value is an integer. it is specified by counting how far the note lies above or below the A note that orchestras use in tuning   ( https://en.wikipedia.org/wiki/A440_(pitch_standard)  if needed to check )   . In counting "how far", you should count every key, both the white and black notes on a piano. So the A note above Middle C would have a value of 0. The A note one octave above that would have a value of 12. The default constructor should set a note to a A440 (an A note of frequency 440Hz) quarter note. Include methods to set a note to a specified length and value. Write methods to retrieve information about a note,…
